Waterloo [Canada], January 27 (ANI): A new study has found that when COVID-19 disrupts homes with two or more children, one sibling is affected more than the other.

The study has been published in the 'Developmental Psychology Journal'.

When caregivers are experiencing stress associated with the pandemic, many other areas of family life are disrupted--often with higher levels of the mental-health struggle for children, including anger, anxiety, and depression.

Researchers found that one sibling tends to present greater mental-health problems. That, in turn, elicits more negative parenting.

"Our study shows that parents tend to be most reactive and least positive to the child showing the highest levels of mental health difficulties," said Dillon Browne, the study's lead author and a professor of clinical psychology at the University of Waterloo.

"Struggles with mental health among family members exacerbate each other in a feedback loop," Browne said.

"Our study suggests that the direction of influence appears to go from the child's mental health to parenting, not parenting to child mental health," he added.

To conduct the study, the research team collected and analyzed data from more than 500 caregivers and 1,000 siblings. Caregivers with two children between five and 18 years old completed questionnaires on COVID stress, family functioning and mental health at repeated times throughout a two-month period during the COVID-19 pandemic.

"Understanding children's mental health difficulties during COVID-19 requires a family system lens because of the numerous ways the pandemic affects the family as a unit. Comprehensive interventions for children's mental health require an examination of caregiver, sibling, and whole-family dynamics," said Browne, who holds the Canada Research Chair in Child and Family Clinical Psychology.

The findings suggested that family therapy, in addition to individual psychotherapy for children and adults, might be helpful for households who are struggling with adjustments in response to the pandemic.

Browne added that future research needs to examine the uptake and effectiveness of family therapy services during the pandemic.

"A lot of research studies have pointed to mental-health challenges associated with the pandemic for children and parents. This work adds insight into how pandemic-related disruption goes beyond the individual and infiltrates the relational environment of the family unit," Brown said. (ANI)
